DRAFT-ABBIANO?) FOR.

To all whom it may concern:

Be it known that I, TRUMAN B. FUNK, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and'usefnl improvements in` Draft Appli-v Sistina the torque'- or the downward thrust .of the rear end of JEhe tractor, due to the operation of the engine, and so that the trailing implement may adapt itselfrby tilting' or rockingon a horizontal axis to inequalities oi the surface of the ground. 'f

A further object of the invention is to so arrange the draft appliance that a low down draft connection' below the axis ofthe wheels will the tractor for use in connection with most of the ground working implements for which it is intendcd.- Further objects are to so construct the connections that they will be strong' and durable, and at the Sametime well fitted for employment with a diverse line of implements..

' Further objects and uses of the invention will appear from a detailed description of the 'invention which consists inthe features of vconsti-notion and eornbinations'of parts hereinafter 'described and claimed.

In the drawing: Figure l. isa sectional view through the tractor, showing the draft appliance of the present invention in side elevation; and Fig. 2 is atop or pian view of the saine.4 The draft features constituting the resent invention are applied to a tractor aving tractor wheels l driven by means of -an engine 2 and suitable Igearing connections 3. `-Tl1e engine andassociated parts are carried by a frame Ll, and are preferably mounted in advance of the axle 5, so that the weight of the engine will in a measure counter-balance the weight onthe draft appliances and Speciicati'n of Letters Patent.

assist the latter in overcoming thetorque of the'engine. '.lhe frame Il, at its rear end, terminates in a standard 6 provided,at its top and bottom, with pivot mountings 7 and 8 respectively, which latter and lower ends 9 andi() of a vertically arranged yoke 11, beine; pivoted to the mountvertical pivot pinsl 12, or' other suitable pivotal appliances. The

vertical Y yoke l1 constitutes the bifurcated 65 end of a. Y-shaped casting, the stem 13 .ofv .which projects to the rear and terminates in a` depending` arm 14' provided, "at its end, with ahorizontal pivot bearing ,15. The stem 13. of the yoke beamsl one on each side of the stem 18, and the beams, at their rear ends, diverge from one another, as shown in F1a'. 2, and are connected, a't the rear ends, 75

to a bridge plate 17 provided on its under side in the center 'with a plvot'bearingllSin hori- Zontal alinement with the pivot bearing 15,7 the arrangementbeingone which affords a very strong and rigid rearward connection 80 for the draftappliances which form the Vsubject matter vention.

The pivot bearings 15 and 18 alord inountings for the a draft yoke 19, the ends of which are bifurcated to embrace the pivot bearings 15 and 18 with which they are connected by means of horizontal pivots 20 and 21 respectively,

particularly of the present xnthe arrangementbeing one which maintains 90 the draft yoke 11i-rigid vertical alinement with Athe beams l0 and Vwhich permitsa sufficient degree of lateral or tilting movement on a. horizontal axis to colnpensate'for the rocking or oscillating motions of the trailing 95 implement, dueV of the ground.

The draft yoke 19, in its center, is bolted or otherwise detachably connected with the to inequalities in the surface tongue 22, pole, or other available front por- 100 tion of a trailing implement, not shown, such as a plow, cultivator, liarrow, or ,other device, with which the tractor is associated.

The yoke 11 is alsorelianneled or otherwise fitted to draft bar 23, the lower end of which is provided with a series of -lioics 2% any one oi' which is'adapted to furnish a connection for a draft rod coi'niected, at its rear end, with the draft yoke 'if' receive the upperis channeled on each and Vreceives the forward forward and rear ends of receive the upper end of a provided with im piante 17, furnish rear or articulated fra-mel work for the tractor andserve as a mountingfor the controlling devices, but these eatures do not constitute s. art ci the present invention, and need not described iii detail.

The arrangement .is one which" adords a vezy rigid connection between 'the tractor an the trailing implement, which is important for the reason that the rearend of the tractor will be supported upon the trailing implement at e considerable distance from the tractor wheels, so that the connections must be of a character which will re sist strains in a vertical direction and at the 'same time aord the horizontal tilting more i ment required in steeringthe tractor and in accommodating the tilting or tipping more` ments of the trailing implement in riding. `over rough ground..

The draft yoke i9 is enmloyed in connection 'with low down machines, suchas ha-rrows, for instance, but .for high draft inacbines, such as cultivators, hay cakes, etc., the yoke may be dispensed with and a connection made directiy between the tongue or pole of the machine/and the horizontal pivot mountings l5 and 19, in which case the draft rod 25 will likewise be dispensed with.
